For a long time Californians have been made aware consistently that the “big one” is coming. Someday a massive earthquake is certainly going rip through the San Andreas Fault, possibly triggering thousands of casualties and billions of dollars in damage. So far nothing that severe has happened in recent memory. With the exception of the 1906 San Francisco earthquake, the state has been for the most part spared from any serious tectonic catastrophe.
But as outlined by some experts we might not have to wait much longer, particularly in regards to the southern portion of the San Andreas fault near San Diego and Los Angeles. That’s because it’s been so long since this fault has had an earthquake. The pressure is building there. The fault generally has a major earthquake every 100 years or so, but this specific portion hasn’t experienced a major quake since 1857, which was a magnitude 7.9.
